The K&N 57-1570 is a 57 Series FIPK (Fuel Injection Performance Kit) cold air intake for the 3.0L V6 turbo diesel in the Jeep Grand Cherokee WK2 (3.0 EcoDiesel). It replaces the factory air filter, air intake housing, and intercooler pipe with a free-flowing high-density polyethylene tube, a high-flow K&N filter, and a heat shield that fills the original air box space. The intake tube also accepts the factory mass air sensor, so the sensor stays in the stock position.
Compared with the stock restrictive airbox, the manufacturer's design aims to reduce intake restriction and feed the turbo inlet with a smoother, straighter airflow path. The filter is washable and reusable, and the manufacturer rates it for up to 100,000 miles depending on driving conditions, which offsets the recurring cost of disposable paper filters. The kit is backed by K&N's Million Mile Limited Warranty. Searchers looking for a 2014-2016 Grand Cherokee EcoDiesel cold air intake, a reusable diesel intake filter, or a WK2 3.0 diesel FIPK kit will find this part fits that description.
Yes. The manufacturer's installation sheet includes one set of steps for 2015 and earlier vehicles and a separate set for 2016 and later vehicles, so follow the section that matches your truck.
According to the manufacturer, disconnecting the negative battery cable erases pre-programmed electronic memories, so write down memory settings first. The manufacturer also notes that some radios require an anti-theft code after reconnection, which is typically listed in the owner's manual.
The manufacturer states the filter lasts up to 100,000 miles before service is required, depending on driving conditions. The filter is washable and reusable rather than a disposable element.
The manufacturer describes the installation as usually taking 90 minutes or less, using the vehicle's existing factory mounting points. Start by turning off the ignition and disconnecting the negative battery cable, and record radio presets and other memory settings beforehand. The heat shield, filter adapter, and intake tube are mounted and connected in sequence, and the mass air sensor and crankcase vent connections need care during reassembly. Because the instruction sheet splits steps by model year, check the 2015-and-earlier or 2016-and-later section before you begin.
